He's only working with 6 cubic feet of total space. This is a tiny area for a normal grow, nevermind a dual-chambered veg and flowering area. I can't see you harvesting more than a few grams per harvest with this sort of setup. You'd be better off scrapping the perpetual growth idea until you can get more space to work with. And even with a normal grow, I wouldn't put more than one plant at a time in there. You'll get the biggest yield by focusing on one single plant that you top, pinch, and tie down.
